"JAR-CLOSURE.

SI- EGIFICAT ION forming part of Letters Patent No. 691,696, dated January 21, 1902.

Application filed May 16, 1901.

To all whom it may concern:

TIN, a citizen of the United States, residing at San Francisco, inthe county of San Francisco and State of California, have invented a new and useful Jar-Closure, of which the following is a specification.

My invention is an improvement in jar-closures, and has for its object to provide a simple, cheap, yet effective device for locking the top of a jar in position.

The object of my invention is to provide a device that can be quickly and easily attached or detached to or from a jar and when in po sition will firmly clamp the top, so that air or moisture will be excluded from the jar.

With the above object in view my invention consists in certain new combinations and arrangements of parts, as will be fully described in the following specification and pointed out in the appended claims, reference being had to the accompanying drawings, in which+ Figure l is a perspective view of the upper portion of a jar with my improvements applied. Fig. 2 is an enlarged section on the line 2 2 of Fig. 1. Fig. 3 is a plan view. Fig. 4 is a detail view illustrating the manner of securing the levers to the base. detail viewof a portion of the frame. Fig. 6 is a detail view of one of the clamping-arms. Fig. 7 is a detail horizontal section on the line '7 7 of Fig. 2, and Fig. 8 is a detail section on the line 8 8 of Fig. 7.

In the drawings, A designates the jar, which is of the conventional shape, having a flange 'a near the upper end, upon which is placed the usual packing-rin g, upon which theflange of thetop B rests. The lower face of the flange, is undercut or inclined upwardly, as shown at a and as most clearly shown in Fig. 2.

My improvement is so constructed that it can be applied to the jars now generally used and consists of a base C, having four arms a.

diverging from the center thereof, which ex tend-nearly to the edge of the top B, and having their upper surfaces beveled, as shown at 0. At a point adjacent the beveled ends the arms are provided with pins 0 which. are formed integral with the said arms and whose ends are bent over toward the sides of the Fig. isa

arms, the purpose of which will appear later on.

D designates a series of lovers or arms, one being arranged in position upon each of the arms of the base and having an aperture (1 near their outer ends, through which is passed the pins 0 that retain the levers in place. These openings are elongated at the upper portion of the levers, said elongations running the length of the levers, as clearly shown and for the purpose as will also appear later on. provided with apertures d, through which are passed the shanks of clamping members F, which are bent over at the ends, forming eyes f, that encircle the ends of the levers and by which the said members are retained in place. The lower ends of the clamps are provided with foot portions f, whose upper surface is beveled or inclined to fit under the flange, and in order to adjust the foot portions in .place without entirely unfastening the screws H, I provide the flange with cut-out portions a to receive the inclined foot-sections, as will be described later on.

In order to adjust the clamps, I provide the inner ends of the lever D with apertures d that receive the ends 9 of a clamping-plate G, whose center is provided with an aperture through which-is passed the shank of a clam ping-screw H, which enters a screw-threaded aperture in the center of the base-plate (J. In practice I prefer to bend the ends 9 of the clamping-plate to encircle the ends of thelevers, which prevents any accidental displacement or loss of the several parts.

The operation of my improvement is as follows: After the top has been placed on the" jar my improved clamp is arranged in position so that the clamping members proper hang down the sides of the jar, the foot portions registering with the cut-out sections in the flange. The top is then given about onequarter turn, so that the clamps will restbetweenthesaidcut-outsections. Thenbyturning the screw the inner ends of the levers are drawn down and the outer ends correspondingly raised, which draws the clamps up under the flange and tightly clamps the top in place.

It will thus be seen that I provide a simple arrangement of parts that can be quickly and The extreme outer ends of the levers are easily adjusted, and by making the upper surface of the foot portions of the clamps beveled to fit a correspondingly-shaped flange all possible danger of the clamps slipping is avoided.

By providing the bevel surface at the outer ends of the arms I obtain a fulcrum for the lever at the juncture of the bevel and the flat horizontal surface of the arms, and to prevent the arms being disengaged the pins are bent at right angles to the body portion thereof. Now to position the levers on the arms of the base the former are turned crosswise to the length of the arms on an angle, as shown in dotted lines in Fig. 4. The pins being inserted in the apertures, the arms are then brought to ,a horizontal position, as shown in full lines in said figure, when they are swung around to their operative position. This operation I am enabled to obtain by making the upper end of the aperture elongated, which permits the passage of the angle portion of the pins, as will be readily understood.

Having thus fully described myinvention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

l. A jar-closure comprising a base-section having arms diverging from the center thereof, levers pivotally held upon the said arms, clamping-sections having their lower or foot portions arranged for engagement with the flange of a jar, a clamping-plate connected to the inner ends of the said lever, and a screw connecting said plate to the base, substantially as shown and described.

2. A jar-closure comprising a base-section having arms diverging from the center thereof, and having the outer ends beveled upon the upper side, pins formed integral with the said arms, levers provided with apertures for engagement with said pins and having their extreme ends also provided with apertures, clamping members connected to the outer ends of said levers, a clamping-plate for engagement with the inner ends of said levers, and means for adjustably connecting said clamping-plate and base, substantially as shown and described.

3. In a jar-closure, the combination of a base-section having arms diverging from the center thereof, the outer ends of the said arms being beveled upon the upper side, retainingpins formed on the said arms and having their upper ends bent at right angles to the body of said pins, levers having apertures for engagement with said pins, clamping-sections loosely held upon the outer ends of said-levers and having the upper surface of their foot portions beveled, a clamping-plate connected to the inner ends of said levers, and means for connecting said plate and base-section, substantially as shown and described.
